	Hi all! We are investigating about how OpenEMPI can link a same person or similar persons into from different domains into one. I mean, we would like to know if OpenEMPI is able to link different persons that it considers that both are the same person. How does it make it? And how this feature can be tested by the core code? Thanks very much

	It can link similar persons together, it is one of the main purpose of OpenEMPI. You can see test codes in the source code tree. What do you want to do more precisely?

	Hi, We are wanting to make a SOAP interface and one of the main operations would be to extract all patients linked to each others. If OpenEMPI covers that, how can be restrict the matching criteria for this purpose? Thanks very much

OpenEMPI can perform exact matching with multiple fields and Fellegi-Sunter probabilistic matching with multiple fields with wide variety of distance metrics. All this is configurable through XML and UI (under development). A basic blocking algorithm decreases the record linkage time.
After matching you will be able to query linked Person entities, see the PersonLinkDao interface.
PersonLinkDao is a low level interface, I just mentioned so you get better idea what is going on under the hood. OpenEMPI has EJB3 interfaces, no SOAP interfaces yet.

	Additional information when we speak about record linkage. OpenEMPI itself is capable of performing deduplication. This is a special case of record linkage, when you have one dataset with multiple entries. The "person" database table contains the core of the patient records. The example FEBRL datasets contain multiple altered entries.
